WhatsApp is a popular messaging app used by billions of people around the globe. It’s become so popular over the past decade that even businesses are taking advantage of it to market and up their communication game with customers.


Whether or not you’re familiar with WhatsApp (and we bet you are) or are simply looking to learn more about it, you’ve come to the right place.

In this post, we’ll dive into some of the most commonly asked questions about WhatsApp. We’ll be talking about the WhatsApp Messenger app for personal use, the free WhatsApp Business app, as well as the WhatsApp Business API.


So if you’re ready, let’s get straight to it.


WhatsApp Messenger

1. What Is WhatsApp?

Let’s start off with the basics: What is WhatsApp? WhatsApp is the world’s most popular messaging app with two billion users worldwide. It was created by former Yahoo! Employees Brian Acton and Jan Koum and released in 2009.


In 2014, WhatsApp was acquired by social media giant Facebook for $19 billion.


2. How To Add a Contact To WhatsApp?

To add someone on WhatsApp, you need their WhatsApp-registered mobile number. This is often also their actual mobile number, although not necessarily always the case.


Add the contact number to your phone book—don’t forget to include the country code. Once that’s done, if the contact has a WhatsApp account under the number you’ve just added, the WhatsApp symbol will appear on the contact’s profile. Tapping on it allows you to start a WhatsApp conversation with them immediately.


3. How Does WhatsApp Work?

WhatsApp works like any messenger app, except it has more than just basic functionalities. Aside from sending plain text messages, WhatsApp also allows its users to send emojis, gifs, and stickers, as well as place voice and video calls. 


Users can also share their live location, leave voice messages, and send multi-media files including images, videos, documents, and audio files.


4. Is WhatsApp Safe?


Yes, WhatsApp is safe. It uses end-to-end encryption to ensure messages are safe and secure even before it is sent out.


This also means that no one other than the sender and recipient can read the contents of the chat—no, not even WhatsApp themselves.


5. How To Block Someone on WhatsApp?

To block a contact on WhatsApp, go to their profile by entering the chat and tapping on the top bar where their name/phone number and calling options are located.


Scroll down to the bottom and tap on the “Block” option. You will be prompted to confirm whether you want to proceed with blocking the contact.


6. How To Delete WhatsApp Group?

To delete a WhatsApp group, you must first leave the group. Go to the page with the group’s info by tapping on the top bar. Then, scroll to the bottom to select “Exit group.” 


Alternatively, long-press the group chat while on your list of chats, select the three vertical dots at the top right-hand corner, and select “Exit group.” 


After you’ve left, you will be able to delete the group with a long-press on the chat and tapping on the bin icon that appears at the top.


7. How To Delete WhatsApp Messages?

Long-press on the specific message(s) you’d like to delete to bring up possible actions on the top bar. Tap on the bin icon to delete the messages.


If you’d like to delete an entire chat, long-press the chat while on your list of chats and tap on the bin icon.


8. How To Recover Deleted WhatsApp Messages?

The only way to retrieve WhatsApp messages that have been deleted is by restoring a backed-up version of your WhatsApp chats. 


By default, WhatsApp creates backups at 2 am every day. Note that only messages that have been deleted after the previous backup can be restored.


9. What Does “Last Seen” Mean on WhatsApp?

“Last seen” on WhatsApp tells you when a contact was last using WhatsApp. This is not an indication of whether a message was read or any other sort of activities he or she may have carried out on WhatsApp. It simply tells you when WhatsApp was last accessed.


10. How To Create a WhatsApp Group?

To create a WhatsApp group, open WhatsApp and tap on the three vertical dots on the right-hand corner. This will bring up a menu with the option to create a “new group.”


Then, select the participants you’d like to include in the chat and click next (the green arrow). You’ll be asked to type a group name. You can also include a group image/icon if you wish.


WhatsApp Business App and API

11. How To Install WhatsApp Business?


To install WhatsApp Business, go to Google Play Store (for Android devices) or Apple App Store (for iPhones), search for “WhatsApp Business,” and tap on the “install” button. 


Once installed, you may set up your WhatsApp Business account.


12. How Does WhatsApp Verify Business Accounts?

To verify a WhatsApp Business account, WhatsApp sends a six-digit verification code to the number used to register for the account. This may be a landline or a mobile phone number.


The code is sent either via SMS or a phone call.


13. How To Get Green Tick on WhatsApp?

The “verified” green tick on WhatsApp is only available for users of the WhatsApp Business API. Getting it requires going through an official WhatsApp Business Provider.


Here’s more on how to apply for the WhatsApp green tick verification.


14. Can WhatsApp Business Be Used on Two Phones?

The free WhatsApp Business app by WhatsApp can only be used on one phone with one user. Installing the app with the same account on a separate device is not supported.


This is, however, possible if you’re using WhatsApp Business apps created and developed by WhatsApp’s Business Solution Providers (BSPs) that run on the WhatsApp Business API, such as WATI’s WhatsApp Business mobile app.


15. How To Switch From WhatsApp To WhatsApp Business?

First, download the WhatsApp Business app. When entering the phone number you want to register your WhatsApp Business account with, enter the number you’re currently using for WhatsApp Messenger. You will then be prompted to transfer your number to a WhatsApp Business number.


Do not close the WhatsApp Business app while the transfer is still in progress.


16. How To Add WhatsApp Business Number on Facebook Page?

Adding a WhatsApp Business number on your Facebook page requires you to first connect your WhatsApp Business account to your Facebook page.


After that, it’s as easy as adding a button to your page. For more information, check out our guide on how to create Facebook ads that click to WhatsApp.


17. How To Call a Business on WhatsApp?

Calling a business on WhatsApp is just like calling a personal contact. Simply go into the WhatsApp chat with the business and click on the phone symbol located at the top bar. You can choose between starting a voice call and a video call.

18. How Much Does WhatsApp Business Cost?

The WhatsApp Business app is completely free to download. 

Accessing the WhatsApp Business API will incur charges. These include charges to send messages as well as any additional fees that business service providers (through which you need to go to gain access to the WhatsApp Business API) may apply.

19. Is WhatsApp Business Account Safe?

Just like WhatsApp Messenger for personal use, messages sent to and from WhatsApp Business accounts are end-to-end encrypted.

20. What Can WhatsApp Business Do?

WhatsApp Business allows you to increase the interaction and the number of touchpoints you have with your consumers. In turn, it helps to boost customer service, communication, and consequently, sales and revenue.
